negative number X negative number = positive number

I'm having trouble understanding why negative numbers turn positive when they are multiplied or divided. I understood that negative multiplied positive is negative because I was given the following example:

I am in a submarine and going down -2m every second so in 3 seconds I will be at -6m.

I was trying to find an example in which I could undertand why negative X negative = positive.

Could someone give me an example?

Hi

You are in a submarine and going down -2m every second so 3 seconds before now you were at +6m with respect to now

I've asked this question almost a year ago, but this question has started to bother me again. Now, I just automatically change negative numbers to positive when they are multiplied.

But the more I think about it, I think a little differently. When you multiply positive numbers by each other they get bigger. So, if you mulyiply negative numbers by one another shouldn't they get smaller?

Does multipliying and dividing have a deeper meaning that I'm not grasping? What's the meaning of negative numbers? I know that they exist on the number line.
